PAPER-BOX MACHINE.

Specification of Letters Patent. Patented Dec. 10, 1918.

Application filed July 3, 1917. SerialNo. 178,362.

To all whom it may concern:

Be it known that I, OTIs R. HINOHER, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Paper-Box Ma chines, of which the following is a specification.

This invention relates to the manufacture of paper boxes and, more particularly, to candy boxes having top and bottom elements which extend as flanges from the cover or body members of a box.

The object of the present invention is the provision of improved means for securing the referred-to type of top or bottom elements to the box sections in a more eflicient and expeditious manner than hitherto, to produce a neat-appearing and substantial box structure.

With; these ends in view, the invention consists in the novel construction, adaptation and combination of devices, as will be hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view in rear elevation of a machine embodying my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a sectional view through 3-3 of Fig. 1 with parts omitted. Figs. 4 and 5 are sectional views through H and 5-5 of Fig. 1 illustrating the respective cams and the parts actuated thereby but in operative positions different from those in which they are represented in Fig. 1. Fig. 6 is a sectional view taken substantially through 66 of Fig. 2. Figs. 7 and 8 are detail elevational views to an enlarged scale to illustrate the action of a folding and pressureblock with respect to the work which, for clearness, is shown in section. Fig. 9 is a transverse sectional view through one of the referred-to blocks and the supporting connections therefor. Fig. 10 is a perspective view of a box body. Fig. 11 is a similar view of a box bottom member; and Fig. 12 is a similar view showing the box body and bottom connected through the instrumentality of an attaching paper as efiected by the present invention.

The reference numeral 15 represents the machine frame which may be of any suitable shape or construction. J ournaled in bearing boxes of the frame is a transversely arranged cam shaft 16 which is intermittently rotated from a power-driven shaft 17 through the medium of mechanism such, for example, as illustrated in Figs. 1 and 2; said mechanism includes a clutch having a member 18 adapted to be moved into engaged position with respect to its companion member by means of an operatively connected foot pedal 19.

F ixedly secured to said cam shaft are cams, indicated by 20, 21, 22 and 23, adapted to impart movements to the various associated operative parts of the machine.

Mounted for vertical reciprocatory movements in a guide 24 of the frame is an upright bar 25 having a flanged lower extremity 25 to which is detachably connected, as by bolts 25 a form 26 of a size to fit. into the box-body A, Fig. 10. Thebar 25, as shown, is connected by a link 27 to a lever 28 fulcrumed at 29 to a bracket support 15 of the frame and operatively connected by a rod 30 to an arm 31 of a second lever (Fig. 2) fulcrumed at 32. The other arm 31 of said second lever carries, preferably, a roller 33 to track upon the periphery of the cam 20 which serves in each complete rotation of the cam shaft to present the form 26 at various elevations and in opposition to the combined weight'of the bar and the parts associated therewith.

Movable vertically in a guide 34 provided on the frame and in axial alinement with the bar 25 and form 26, is a post 35 having at its upper end a detachable platen 36 of length and width slightly greater than the corresponding dimensions of the box-top B, Fig. 11. Said post is connected by a link 37 (Fig. 3) with the arm 38 of a lever fulcrumed at 39 and carries on its other arm 38 a roller 40 which tracks on the cam 21 which is characterized by having in its periphery two concentric arcs 21 21 at different radial distances from the shaft axis for the purpose of maintaining the post 35 and the platen thereof at two elevations during portions of each rotation of the cam shaft.

Positioned upon members 15 and 15 respectively, of the machine frame, are longitudinally and transversely disposed supports 41 and 41 Secured to the supports ll are attachments 42 having spaced apertured arms 42 in which are journaled trunnions 43 provided on the ends of transversely arranged blocks as, the latter having intermediate their lengths lever arms 4& which are connected by links as with a coupling bar e6 which, in turn, is connected by a link e7 (Fig. 6) with an arm &8 of a lever which is fulcrume-d at 49 and carries by its other arm 48 a roller 50 which tracks on the periphery of th cam 22. The periphery of this cam, as shown in Fig? #1, is provided with a circular part 22 concentric to the cam axis and extending approximately threefourths of a complete circle, and with a peripheral part 22 of the cam portion 22 which protrudes from such circular part.

Slidablv mounted upon the blocks 1% are rectangular casings 51 (Fig. 9), each being connected to the respective block by bolts 52 secured to the casing and extending through holes, such as 14?, in the block to receive on their threaded protruding ends nuts 53 for regulating the extent of separation of the respective casing and supporting blocks due to the action of interposed springs 54.

Attachments having apertured arms 55 are likewise secured to the transverse supports 41 for tiltably holding blocks 57 by trunnions 56 provided thereon; these blocks, like the aforedescribed blocks 44, are provided with lever arms 57 and connected by links 58 with a coupling bar 59 the latter being connected by a link 59 (Fig. 5) with an arm 60 of a lever fulcrumed at 61 and carrying a roller 62 to track against the periphery of the cam 23. This cam is formed at diametrically opposite sides with arcs 23 concentric to the cam axis and, between the adjacent extremities of such arcs, at diametrically opposite sides, is provided with protuberances 23 Similarly to what is shown in Fig. 9 with respect to the blocks at. the blocks, 57 have slidably mounted thereon casings 63 (Figs. 7 and 8) which are each yieldingly held by means of springs 64: in its outermost position with respect to the block 57 therefor.

The supports 41, 41 are arranged to be regulated to present the casings 51, 63 and the respective blocks therefor, closer to or farther from the axis of the form 26 and platen 3?) according to the size of the lat ter required in a particular run of work.

When properly adjusted. said supports are secured as by means of clamping screws.

The operation of the invention may be explained as follows:

The operator standing in front of the machine places a box top B upon a piece of attaching paper C having upon its upper surface acoating of paste. This paper, as indicated by broken lines in Fig. 11, is sgmewhat larger than said top to furnish a projecting part outside of each edge of the top. Theoperator then inserts the top and attached paper into the space between the casings 63 when occupying the positions in which they are represented in Fig. 3, and when the platen is in its uppermost position as shown in this view.

Th space between said casings is, however, only suiiicient to accommodate the thickness of the paper in addition to the width of the top; hence the side edges of the paper are turned up, as indicated by C in Fig. 7

The operator places a box body A upon the form 26 to be brought down therewith onto the top, whereupon the cam 23 effects the elevation of the coupling bar 53-) and the links 58, thereby acting through the medium of arms 57 to tilt the blocks and associated casings into the positions in which they are shown in Fig. 5, resulting in the paper margins C at each side of the box being folded at C and C as illustrated in Fig. 8, and causing, moreover, the paper to be pressed firmly against the opposing surfaces A B (Fig. 7) of the body and top, to insure the paper being reliably and smoothly pasted thereto.

\Vhen this has been accomplished, the cam 23 turns into position whereat the casings 63 tilt outwardly to occupy the positions in which they are shown in Fig. 3; the cams 20 and 21 thereupon act in concert to allow the form and platen to lower the work into position to have the ends of the paper 0 be acted upon by the casing 51 to suitably fold the paper and press such ends against the upper surfaces of the protruding ends of the top, and also against the adjacent ends of thebody A. The cam shaft continuing to rotate, then causes the cam 21 to again elevate the platen 36 and the superposed form :26 into positions whereat the casings 63 are again influenced to press down any hummocks obtaining at the corners of the box, and to give the overlapping portions of the paper a practically smooth and neat appearance; the casings 63 are then tilted. outwardly to free the work and allow the same to be withdrawn from the form 26 as the latter ascends during the termination of a cycle of the machines operation.

The several cams, as shown, are arranged to impart lifting movements upon the mechanisms that actuate the form, platen and several casings in the performance of their respective duties and in opposition to the weights thereof, whichserve to restore said form, platen and casings into their retractile or inoperative positions.

Springs. however, may obviously be uti lized to facilitate such inoperative movements.

The construction and operation of the machine will, it is thought, be understood from the foregoing description.
